Enhanced Security for Online Exams Using Group Cryptography
Objective
To improve the quality of Online examinations and to maximum utilize these type.
Existing System
Different cheating patterns exists in current system including copying the answers of others, exchanging answers, searching the Internet for answers, using the data and software saved on the student’s local computer and discussing the exam by e-mail, external storage devices.
Disadvantages

Proposed System
► This project proposes a solution to the issue of security and cheating for online exams. This solution uses an enhanced Security Control system in the Online Exam (SeCOnE) which is based on e-monitoring scheme. The e-monitoring provides a proctor function to remote examinees to prevent cheating, and thus removes the requirement of having to go to a fixed location. The target of this project is online exams of any type and exams in online university courses with students at remote locations.
► Project proposes administering an online exam at a fixed time with the same questions for all examinees, just like an off-line exam, but without restricting the physical location of the examinees. As the SeCOnE system enables many kinds of tests to be given online, it can provide teachers with better evaluation standards for students and may contribute to improving the quality of education.
Scope of the project
This system can provide the secure and prevent the online exam. It can find which candidate cheats the exam through the internet or getting the answer from the local hard disk. It does not allow the cheated candidate to write the online exam.
Advantages
► Online exam management system having some monitoring method to prevent and to detect cheating.
► Without regard to location and time.
► Avoid intercepting or interfering with communications during an online exam.
